(x-3)(3x+1)
(3x + 1)(x - 5)
-3
(x + 2)(3x - 1)(3x + 1)
By factoring I get x-3 divided by x+3
No, unless "a" happens to be equal to 0, or to 1.
sin squared
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
(2x - 1)(4x + 1)
It is (A-1)(A+1) when factored
-8.
It is: 64-1 = 63
2x squared - 5x - 3 = (2x +1)(x -3)
i = sqrt of (-1) ( imaginary) i squared = sqrt(-1) x sqrt (-1) = -1 (minus one)
x + 1
1/x4
x = 1
